Are you feeling it more in the steering wheel or in your seat?

hard to say, its like 50/50 so it could be front or back or maybe a little of both. good thing it is very slight so im hoping its a simple tire or rim issue.
you can really scare the hell out of yourself reading those problems with my vehicle websites when all the problems seam to be identical without much answers for it.

that's good to hear
road force balance (as I understand it) is balancing the tires with the weight of the vehicle pressing down on them, like it sounds, with road force applied to them. its a much more accurate method but im not sure exactly how its done.
I have read some stuff about how the new wheels are molded or cast and not turned from solid metal like they used to be so the center hole is not the true center and cant be used to balance wheels on a traditional wheel balancer.
as I understand it, the reason for road force balancing is that under load the tires may deform throwing the balance off.
now I don't know if road force means its done on or off of the vehicle but I saw talk about "done on the car" balancing machines or special adapters being needed for none centered rims that must be centered using the lug bolts and not the hole
